Updated 11 October 2026

Sea Pals brings BTS fans together through pen pal letters about music. Choose K-pop as an interest and share a listening memory; Mochi looks for people with shared interests to carry your letter to.

## Sample letter

요즘 이 노래만 계속 들어. 너는 최애 곡이 뭐야?

Translation: I keep playing this one song. What’s your favourite?

## Choose your interests

Choose K-pop and any other interests you enjoy, such as music or dancing.

## Write a letter

Write about what the music means in your everyday life and ask another fan about theirs.

## Make a friend

After accepting a letter, keep exchanging listening stories from your island. A song might remind you of a place or a moment you can tell your new friend about.

## What to write about

Start a fan letter with a listening memory or a question about music; your pen pal does not need to have the same favourites.

- Describe a song you keep replaying and the mood it fits.
- Tell a fellow fan how you first found the music.
- Share a concert memory, including a performance you streamed at home.
- Describe a dance you tried learning and the part you found tricky.
- Explain how your listening habits have changed since you became a fan.

## Pen pal privacy and age rules

- Someone new never sees your birthday, exact location or username.

- Social handles and links can’t go in letters.

- Teens 13–17 only meet other teens. Country minimum ages apply.
